Abstract (en)
[origin: EP0416612A2] A turret head (14) is mounted on a turret body (10) in such a way that it can be rotated about a turret axis (16) and can be locked in several working positions. At least one tool holder (34) is interchangeably fastened to the turret head (14). The tool holder (34) has a rotatable clamping device (56) for a tool (62) as well as a spindle (52) for driving the clamping device (56) with a gear (53) arranged inside the turret head (14). A drive shaft (80) parallel to the turret axis (16) is mounted so as to be axially displaceable in the turret body (10) and can be loaded by a hydraulically produced axial force. The drive shaft (80) carries a gear (78) which in a working position of the turret head (14) can drive the spindle (52). The drive shaft (80) is preloaded with a low axial force for engaging the two gears (53, 78) and can be locked in place in the axial direction with a hydraulically produced force only after the engagement of the two gears (53, 78). <IMAGE>
